A method and system for stabilizing images being taken by a video camera using electromechanical stabilization. The stabilization system performs inter-frame stabilization based on the velocity of a vehicle on which the video camera is mounted and the pan rate of a line-of-sight controller of the video camera. The inter-frame stabilization is performed by a software component by moving a display area (or viewport) within a larger image area. The stabilization system converts an inter-frame stabilization adjustment into a pan rate adjustment so that the line-of-sight controller will keep the desired object within the image area of the camera.

The invention claimed is: 1. A method for stabilizing an image of an object being taken from a video camera, the video camera being moved by a transport mechanism and being controlled by a line-of-sight controller, the line-of-sight controller having an orientation and an angular velocity, the method comprising:receiving a plurality of images of the object; andfor each of the plurality of received images,receiving a distance from the video camera to the object,determining a difference between the location of the object within the image and the location of the object within a previously captured image,calculating an inter-frame stabilization adjustment based on the distance to the object and the difference between the location of the object within the image and the location of the object within a previously captured image, the inter-frame stabilization adjustment for adjusting the position of a display area of the received images,adjusting the position of the display area of the received images based on the inter-frame stabilization adjustment, wherein the received images are larger than the display area and the adjusting moves the display area relative to the received images, andcontrolling the line-of-sight controller at least in part by,calculating a line-of-sight adjustment for the line-of-sight controller based on the inter-frame stabilization adjustment,adjusting the orientation of the line-of-sight controller based on the calculated line-of-sight adjustment,calculating an angular velocity for the line-of-sight controller based on the inter-frame stabilization adjustment, andsetting the angular velocity of the line-of-sight controller to the calculated angular velocity.
